Cache External Scripts

Description

Often when trying to optimize the Google Pagespeed score, there is one script which still causing the ‘Leverage browser caching’ rule popping up: Google’s own gtag.js and/or analytics.js file…

With this plugin you will be able to cache this file on your local server and enable browser caching for longer than 2 hours. The plugin will check every day if there is a newer version of the file to keep the cache up to date.

Installation

Installation is very easy;

Upload the plugin directory cache-external-scripts to the /wp-content/plugins/ directory or install it directly from the WordPress plugin directory.

Activate the plugin through the ‘Plugins’ menu in WordPress

Once the external script is cached by the plugin, it will automatically replace the url in your current Google Analytics code (meaning you can use your current Google Analytics plugin).

FAQ

I have installed the plugin, but I can’t find the Google Analytics code in the page source code

This plugin only caches the script and replaces it in your current Analytics code, containing ‘gtag.js’, ‘analytics.js’ or the older ‘ga.js’ script.
We chose not to insert the Analytics code itself because there are tons of plugins for that already, and some users require modifications in the code.

How can I check if the Analytics code is properly cached

We store the cached file in the wordpress uploads directory, in the folder called cached-scripts. If this folder doesn’t exist or is empty, please visit the settings page of the plugin to manually fetch the script.
